Note:
This machine data is not included in the machine data lists. During start-up in machine data
dialog, the machine data is set or altered as appropriate via the configuration setting.
This machine data indicates whether the main spindle drive (MSD) is in the bootstrap mode
(MD 97 = 0) or the normal mode (MD > 0). There are two possible options for implementing
booting in the MSD bootstrap mode:
1. The machine data MD 95, MD 96, MD 98 and MD 238 are input; by setting MD 97 to 1H,
the default settings resulting from MD 95, MD 96 and MD 238 are entered for all other
machine data.
2. All machine data are entered, for example, by loading a machine data file. The bootstrap
mode is terminated by setting MD 97 to 2H.
